Effects of Exercise on EEG Activity and Standard Tools Used to Assess Concussion

Table 1

Results from statistical comparison of baseline and postexercise for qEEG spectral bands during the eyes-closed and eyes-open tasks. Wilcoxon rank sum test Z scores, unadjusted values, and false discovery rate- (FDR-) adjusted values are presented for both EC and EO tasks (columns) and for each spectral power band (rows). The only statistically meaningful difference that survived FDR occurred in the theta band (shown in bold).
